Last week we had 34 hours wet, mostly from dew. This gives us a total of 188 hours toward the 250-hour threshold.
Rappahannock County (Washington, VA) had 209 wetting hours as of June 8, and probably will reach the 250-hr threshold for development of sooty blotch and flyspeck on unprotected fruit this week.
Disease management information directed mostly to the Frederick County Virginia tree fruit industry, updated as needed throughout the growing season. Keith Yoder, Virginia Tech Agricultural Research and Extension Center, Winchester, Virginia
